(Cl..131--l184) 3'Claims. 1 AThis invention relates to new and useful improvements and structural refinements in smoking pipes, and the principal object of the invention is to provide a device of the character herein described, which embodies in its construction means for preventing moisture from reaching the mouth of the smoker and further means for prereadily lend itself to economical manufacture.

With the above more important objects in View, and such other objects as may become apparent as this specication proceeds, the invention consists essentially of the arrangement and constrution of parts as illustrated in the accompanying drawings, in which:

Figure 1 is a cross-sectional View of a pipe, showing the invention in situ therein.

Figure 2 is a further cross-sectional view of the pipe bowl and stem portion, illustrating the manner in which the invention is used for cleaning the same.

Figure 3 is a cross-sectional view of the cleaning member per se.

Figure 4 is a cross-sectional view of a tube used in the invention.

Figure 5 is an end View, taken in the direction of the arrow 5 in Figure 3; and

Figure 6 is a side elevational View of the pipe mouthpiece.

Like characters of reference are used to designate like parts in the specification and throughout the several views. y Y

Referring now to the accompanying drawings in detail, the invention embodies in its construction a tube I 0, internally threaded at one end thereof as at II, while its remaining end portion is removably receivable in a counterbore I2 formed in the bore I3 of the pipe mouthpiece I4.

This mouthpiece is provided with an adaptor I5, removably receivable in the bore I6 of the stem portion I1, the latter being, of course, associated with the bowl I8. It will be noted that the threaded end portion of the tube I0 extends into the bore IB in a spaced relation therewith, as is best shown in Figure 1.

`'A cleaning member designated-generallyabyv the Vreference character I9 consists 'Tof fa'cylindrical bodyl provided at .one end'thereofwithLasubstantially frusta-:conical :head .f2 I :while :the :rernaining end is equippedv withra shankofreduced diameter, as1at 22. ',The'freeiendportion of the lshank 22 is externallyzthreaded.assat2`3,:the purpose of Which-is hereinafter moreifully explained. It will be noted inFigurefl that the tube VIII-normally projects outwardly .fromv thexend fof '..the stem a distance greateruthan:thegspacing of :the adjacent ends of :the shankfand'the': tube.

' The member f I disformedwithza longitudinally extending, axial smoke. passage 24,;fandthe head 2I is provided Awith radially disposedsmoke channels 25. It will be noted that. thesmoke. .channels communicate with thepassage 24.

The 'body VZilis removably receivable inzthe bore ISof the stem II, said bore being; formedwatthe entry thereof into the bowl I8 `with avfrusto-conical seatlZG. When Ythe member I9 is insertediin position, the head2 I thereofzzwill .engage therseat 2S, as shown in: Figure 1.

When. the invention isV placed .in use, the device is arranged asshown in Figure 1, .whereinL itgwill be apparentthat the position of thefsmokeichannels 25 and the passage 24in, the head 2 I-willtend to 'preventparticles of tobacco in the bowl lgfrom moving to obstruct the flow' of smokebetweenthe bowl and the.. bore I 5.

They smokelwill, 'of course, travel.Lthroughathe channelsv 2 5 .andthe passage24 intoN theiibore lI 6 andthen through .the tubeLldandthe mouthpiece I4, Ymore specically, .throughvthebore; l3- ofsthe mouthpiece, into the mouth of the smoker. It will be noted in this connection, that any moisture such as may be present in the smoke will be collected in the bore I6 by virtue of the spaced relationship of the tube I0 with respect to said bore.

When it is desired to clean the bore IB, the mouthpiece I4 is separated from the stem portion I'I in the conventional manner, and the tube I0 is withdrawn from the counterbore I2.

The threaded portion II of the tube may then be engaged with the threaded portion 23 of the member I9, whereby said member may be easily and conveniently withdrawn from the bore I6, as is best shown in Figure 2. During this withdrawing operation, any sediment such as may be present in the bore will be effectively removed as indicated at 21.

It is believed that the advantages and use of the invention will be clearly apparent from the foregoing disclosure and accordingly, further description thereof at this point is considered unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What I claim as my invention is:

1. A smoking pipe comprising in combination. a bowl and stem portion formed with a longitudinally extending bore, a mouthpiece separably connected to said stem portion and provided with a continuation of said bore, a tube removably received in the bore of said mouthpiece and projecting into the bore of said stem portion in concentric spaced relation thereto, and a cleaning member comprising a shank disposed in spaced concentric relation in the bore, said shank being provided with a substantially frusto-conical head slidably fitted in the bore, said .bore being formed with a seat adjacent the entry thereof into said bowl, said head and shank having a longitudinal bore therethrough, said head being engageable with said seat, said head being provided with a plurality of smoke passages, said tube and the shank being spaced from each other and having means carried on their adjacent ends for detachably coupling together, said tube projecting a greater distance beyond the end of the stem portion remote from the bowl than the shank and the tube are spaced apart.

2. In association with a smoking pipe, a cleaning and ltering device comprising in combination, a tube screw threaded at one end thereof and removably received at its remaining end in the mouthpiece of the pipe, the screw threaded end portion of said tube extending into the bore of the pipe stem in a spaced relation therewith, and a cleaning member comprising a cylindrical body slidably fitted in the bore and having a substantially frusto-conical head at one end and a threaded shank of reduced diameter at the remaining end of said body projecting in spaced relation to the bore towards the tube, said body,` said head and said shank being formed with a longitudinally extending smoke passage, said head being provided with radial smoke channels communicating with said passage, said body being removably receivable in the bore of said stem with said head partially closing the opening of said bore into the pipe bowl, the shank and the ing bore therethrough communicating with the I interior of the bowl, a mouthpiece detachably secured to the end of the stem remote from the bowl, said mouthpiece having a longitudinal bore therethrough opening into the bore in the stem, a pipe stem cleaning member comprising a head slidably iitted into the bore in the stem and normally positioned closely adjacent the bowl, a shank on said head and supported solely thereby projecting in spaced concentric relation to the stern towards the mouthpiece, said head and nank having a smoke passage therethrough, a tube removably received in the bore of the mouthpiece and projecting in spaced concentric relation to the stem towards the shank, said tube being supported solely by the mouthpiece and terminating in spaced relation to the shank, the adjacent ends of the shank and the tube having complementary screw threads for coupling together, said tube normally projecting outwardly from the end of the stem remote from the bowl a greater distance than the spacing of the shank and the tube, whereby the mouthpiece may be removed from the stern and the tube disconnected from the mouthpiece and the tube reinserted in the stem by itself and coupled to the shank for withdrawing the head from the stem.
